Conductivity of the PGT Synthesized by the High Energy Ball Milling (HEBM)

Conductivity of the PGT Synthesized by the High Energy Ball Milling (HEBM)

Nanocrystalline Pb1−3x/2GdxTiO3 (where x=0.01) abbreviated as PGT has been synthesised by high energy ball milling at room temperature. Milling was continuous and X-ray analysis shows that single phase tetragonal structure of nanocrystalline PGT was formed after 15 h milling. The average crystallite...
